Ancor Heavy Duty Battery Lug – 4/0 AWG, 5/16" Stud, Pack of 2 (VER-81309)
Terminate large-gauge battery cables with confidence using these Ancor heavy duty marine battery lugs. Designed for 4/0 AWG cable — the largest common gauge used in high-current marine applications such as engine starting, bow thruster, and windlass circuits — these lugs feature a thick-wall tinned copper barrel that resists corrosion and ensures a low-resistance, high-integrity crimp connection. Sold as a pack of 2.
Key Features
- Rated for 4/0 AWG (107 mm²) heavy-gauge marine battery cable
- 5/16" (7.9 mm) stud hole — fits standard marine battery terminals and bus bars
- Thick-wall tinned copper barrel for maximum conductivity and corrosion resistance
- Heavy duty construction handles high-current loads from engine starting, thrusters, and windlasses
- Tinned finish protects against saltwater corrosion in bilge and engine bay environments
- Pack of 2 — sufficient for one cable end-to-end termination
- Compatible with hydraulic, mechanical, and hammer-style crimping tools
Correct Termination Matters
At 4/0 AWG, a poor crimp or undersized lug creates resistance that generates heat — a serious fire risk in high-current circuits. Ancor’s heavy duty lugs are dimensioned to ABYC standards, ensuring a proper crimp with the correct tooling and a connection that stays cool and reliable under load.
